Decolorization of acid black 52 by fungal immobilization

Enzyme production by immobilized Phanerochaete chrysosporium using airlift reactor

“…Alternatively, it has been proposed that solid or agitated cultures with fixed mycelium on supports may achieve the best results of MnP action (Nurdan et al 2005;Urek & Pazarlioglu 2005;Park et al 2006). In some cases the bioreactor has also been used to promote the enzyme secretion from free mycelium (Mielgo et al 2001;Shim & Kawamoto 2002;Lopez et al 2004;Enayatzamir et al 2009;Zahmatkesh et al 2010;Pakshirajan et al 2011).…”

“…Important secretion of MnP (1.033 × 10 3 U/L in Direct red 80 and 0.737 × 10 3 U/L in Mordant blue 9) and LiP (1.025 × 10 3 U/L in Direct red 80 and 1.006 × 10 3 U/L in Mordant blue 9) was also produced under these conditions. Recently, moreover, immobilization of fungal biomass by entrapment cell has been studied as a technique to increment the efficiency of metabolic activities (Yesilada et al 2003;Radha et al 2005;Park et al 2006;Zhang et al 2008). Several tests have demonstrated that mycelium immobilization with fragments of pellets is also an efficient method to improve the performance and economic feasibility of many fermentation processes (Kaushik & Malik 2009).…”

“…Apart from agitation, fungal immobilization can also provide a suitable low-shear environment for ligninolytic system of fungi. Immobilize culture of P. chrysosporium on supports like polyurethane foam has often been reported for decolourization of various dyes (Minussi et al 2001;Urek & Pazarlioglu 2004;Park et al 2006). Shim & Kawamoto (2002) studied the enzymes production from P. chrysosporium using a batch reactor system.…”

An intensified degradation of phenanthrene with macroporous alginate–lignin beads immobilized Phanerochaete chrysosporium

“…The immobilized culture is more effective in shielding environmental perturbations such as pH and toxic chemicals in comparison to suspension culture [5]. In practice, calcium alginate has been extensively tested to encapsulate enzymes and living cells [6,7] used for the treatment of metal ions [8,9], dyes [10,11] and phenol [12]. One major problem with this matrix is its high resistance to mass transfer within the dense gel layer [13].…”

Removal of perrhenate anions in aqueous solutions using anion-exchange organic/inorganic hybrid nanoporous beads

“…Syntheses of bead type materials: In order to prepare bead type materials, powder samples were mixed together with Na-alginate solution [24]. To prepare bead type HMS material (B-HMS), 10 ml of Na-alginate solution (4%, w/v) was mixed with 0.75 g of HMS.…”
